Figure 2 This is a flowchart of a control method for a battery swapping system according to one embodiment of the present invention, such as... Figure 2 As shown, the process includes the following steps:

[0032] Step S31: Obtain the temperature information and voltage information of the battery swapping system. The temperature information includes at least the first temperature of the cooling water outlet of the battery swapping system, the second temperature of the battery swapping connector of the battery swapping system, and the third temperature of the single-pole battery swapping interface of the battery swapping system.

This improves control safety and solves the problem of insufficient safety in existing battery swapping systems due to their simple control strategies.

[0035] like Figure 3 The diagram illustrates the structural principle of a battery swapping system. This system is primarily used in electric vehicles. The battery is connected to the swapping frame via a snap-fit ​​connection. The core components of the system are the snap-fit ​​battery, the vehicle control unit, the MCU, and the reverse pre-charge module. The system mainly includes: core components of the snap-fit ​​battery, the vehicle control unit, the MCU, and the reverse pre-charge module.

[0036] It should be noted that the cooling water outlet ( Figure 3The outlet shown is connected to the coolant in the water-cooled plate for draining the coolant.

[0046] Figure 4 This is a schematic flowchart of a control method for a battery swapping system according to one optional embodiment of the present invention. Figure 5 As shown, the method includes the following steps:

[0047] During the high-voltage start-up phase of the vehicle, the vehicle control unit first determines the user's intent and the vehicle's status, initiates a high-voltage power-on request, and proceeds to high-voltage energy control step 10:

[0048] Step 1: The BMS determines whether the battery swapping lockout signal is normal. If it is not achieved, it proceeds to step 10.

[0049] Step 2: The BMS checks whether the high-voltage interlock signal of the battery swapping connector is normal. If it is not achieved, it jumps to step 10.

[0050] Step 3: The BMS determines whether the battery outlet temperature is normal. If it is not greater than 70°C, proceed to step 4; if it is greater than 70°C, proceed to step 10.

[0051] Step 4: The BMS determines whether the temperature sensor 1 of the battery swapping connector is normal. If it is not greater than 125°C, proceed to step 5; if it is greater than 125°C, proceed to step 10.

[0052] Step 5: The BMS determines whether the temperature sensor 2 of the battery swapping connector is normal. If it is not greater than 125°C, proceed to step 6; if it is greater than 125°C, proceed to step 10.

[0053] Step 6: The BMS sends a power-on request to the vehicle control unit; upon receiving the power-on request from the BMS, the vehicle control unit determines that there is no fault in the vehicle and enables the DC-DC converter to perform reverse pre-charging.

[0054] Step 7: The DC-DC converter uses a boost module to convert the 12V battery voltage into a high-voltage output to charge the MCU's high-voltage capacitor;

[0055] Step 8: The vehicle control unit checks whether the DC side high voltage circuit voltage has reached the target value. If it has, it jumps to step 9. If it has not reached the target value within the specified time, it jumps to step 10.

[0056] Step 9: The BMS drives the main relay + and main relay - to close. The BMS determines whether the positive and negative voltages of the battery swapping connector are normal. If they are normal, the high-voltage power-on process is completed. If they are abnormal, the process jumps to step 10.

[0057] Step 10: The BMS requests a high-voltage power-off. The vehicle control unit guides the high-voltage power-off process according to the vehicle status and reports a high-voltage power-on fault to the backend.

[0058] Figure 5 This is a schematic diagram illustrating the flow chart of a control method for a battery swapping system according to one optional embodiment of the present invention. Figure 5 As shown, the method includes:

[0059] After the BMS detects an over-temperature fault at the battery swapping interface, it executes high-voltage protection control steps based on the severity of the fault:

[0060] Step 20: If the BMS detects that either temperature sensor 1 or temperature sensor 2 of the battery swapping connector is greater than 200°C, it will report a serious over-temperature fault of the battery swapping connector interface to the background, drive the excitation fuse to work, and jump to step 22; if neither temperature sensor 1 nor temperature sensor 2 of the battery swapping connector is greater than 200°C, it will jump to step 21.

[0061] Step 21: If the BMS detects that either temperature sensor 1 or temperature sensor 2 of the battery swapping connector is greater than 140°C, it will report a general over-temperature fault of the battery swapping connector interface to the background and jump to step 22; if neither temperature sensor 1 nor temperature sensor 2 of the battery swapping connector is greater than 140°C, it will jump to step 23.

[0062] Step 22: The BMS sends a high-voltage power-down request to the vehicle control unit. The vehicle control unit prompts the user with vehicle fault information based on the vehicle status, guides the completion of the high-voltage power-down, and the BMS drives the main relay + and main relay - to disconnect and jumps to step 26.

[0063] Step 23: If the BMS detects that either temperature sensor 1 or temperature sensor 2 of the battery swapping connector is greater than 125°C, it will report an over-temperature alarm for the battery swapping connector interface to the background and jump to step 25; if neither temperature sensor 1 nor temperature sensor 2 of the battery swapping connector is greater than 125°C, it will jump to step 24.

[0064] Step 24: If the BMS detects that either temperature sensor 1 or temperature sensor 2 of the battery swapping connector is greater than 1.5 times the calibrated value, it will report the abnormal contact resistance of the battery swapping connector interface to the background and jump to step 25.

[0065] Step 25: The BMS sends a power reduction output request to the vehicle control unit. The vehicle control unit, based on the vehicle status, prompts the user with vehicle alarm information, guides the completion of high-voltage power reduction output, and jumps to step 26.

[0066] Step 26: The BMS determines whether the battery swapping lock signal is normal. If an abnormal signal is detected, it reports a fault in the battery swapping lock mechanism. If no abnormal signal is detected, it proceeds to step 27.

[0067] Step 27: The BMS determines whether the high-voltage interlock signal is normal. If an abnormal signal is detected, it reports a mechanical fault in the battery swapping connector or poor contact of the high-voltage interlock terminal. If no abnormal signal is detected, it proceeds to step 28.

[0068] Step 28: The BMS detects the temperature of the battery outlet. If the temperature of the battery outlet is greater than 70°C, a battery cooling system fault is reported; if the temperature of the battery outlet is not greater than 70°C, a battery swapping connector terminal fault is reported.

[0069] In other words, the technical solution of this application provides an energy management and control method for a battery swapping system, as well as a strategy and method for over-temperature protection and over-temperature fault diagnosis of the battery swapping interface. The technical solution of this application achieves the following technical effects:

[0070] 1. A snap-fit ​​high-power water-cooled battery swapping system is provided. The battery swapping connector transfers heat to the water-cooling plate through the copper busbar connected to the battery system to achieve cooling of the battery swapping interface. This can effectively reduce the high-voltage connection temperature of the battery swapping system, enabling the battery swapping system to meet the high-power charging and discharging requirements of the vehicle.

[0071] 2. A high-voltage power-on control method for a snap-on high-power water-cooled battery swapping system is provided. The method detects the battery swapping lock signal, the high-voltage interlock signal of the battery swapping connector, the battery outlet temperature, and the high-voltage electrical connection temperature to ensure the reliability of the battery swapping system's power-on. The method utilizes the DC-DC reverse pre-charge function to charge the MCU's high-voltage capacitor to the pre-charge target value. Then, the BMS drives the main relay + and main relay - to close, completing the high-voltage power-on.

[0072] 3. A mechanism for handling over-temperature faults of a snap-on high-power water-cooled battery swapping interface is provided. Through tiered handling, personnel safety and vehicle system stability are ensured: For faults exceeding 200°C, the excitation fuse is activated and a high-voltage power-down strategy is implemented to prevent the risk of battery thermal runaway caused by over-temperature and overcurrent faults, ensuring personnel safety; For over-temperature faults of the battery swapping interface within the 140°C to 200°C range, the user is alerted to the vehicle fault and guided to complete the high-voltage power-down; For over-temperature risks or contact resistance exceeding 1.5 times the rated value within the 125°C to 140°C range, the power output is reduced to prevent further damage to the battery swapping system.
